Ways Maintenance on My Mini Split System Differs from the Maintenance on a Standard HVAC System

A mini-split system offers convenient heating and air conditioning services in homes where running new ductwork or using the existing ductwork is not an option. In many ways, it’s similar to a traditional HVAC system. However, there are some important differences when it comes to maintenance.

Checking and Cleaning Mini Split Filters

The air filter on a traditional HVAC system is typically found indoors, next to the main body of the unit. In a mini-split system, the filter is inside the interior unit under the front flap. Locate two clasps on either side of the front panel, typically at the bottom. Slide or flip them out of the way and lift the cover up.

From there, you’ll be able to see the air screens on either side of the unit. To remove them, you might be able to pull them away from the unit with little effort. Depending on the model, however, there may be clips on either side to keep them in place. The air screens should be cleaned thoroughly to remove any dirt or dust buildup.

Behind the air screens, you’ll find the filters. These small rectangles of sponge or foam perform different roles based on their colors. The blue one is an ion filter and works to reduce odors. These typically last up to 3 years. The white filters need to be changed every 3 to 12 months, depending on brand and indoor air quality. They’re responsible for clearing contaminants from the air before allowing it to move through your HVAC system.

Scheduling Regular Maintenance

Similar to any other heating or cooling device, your mini-split system needs seasonal maintenance to keep it performing at its best. Drain line cleaning, checking components for wear and ensuring seals are tight are just a few of the essential tasks your technicians will perform during a visit.
